Abstract A series of maleates with different metal cation were prepared, and their effects on PVC thermal stability were investigated in this work. The results show that maleates can improve the static stability and the colour stability of PVC on a high level, especially for maleic sodium and maleic zinc. The molecular structure and metal cation were thought to influence the stability effect of maleates. The thermal stability mechanism of maleates can be summarized as follows. Maleates can substitute or chelated the
unstable chlorines in PVC chains, or absorb HCl on the one hand, can react with the conjugating double bonds by the Diels-Alder reaction on the other hand.
